You may not be able to check in documents (or individual diagrams) and the Client will present you with an error dialog "An item already exists with that name" or "Invalid pointer" (with the detailed error message stating "Error Number: 0x80004003").
When you check out an item, iGrafx extracts it from the repository and places a copy in a working folder on your local drive (the working folder is controlled by the Repositories menu Options command; see Repository Options dialog box). When you make changes to a document, you are working with this copy of the item.
When using the "Save As..." functionality and through file corruption because of hard disk issues, the identifier connecting the version of the
.igx file on your computer (within your local repository folder) with the file in the repository can become out of sync. If this happens, the check-in process will fail with the above error messages.
Unfortunately, there is no way to restore the original identifier within your copy, but here are two ways to re-apply your changes to a fresh copy from the remote repository.
